BRUSH HANDLE ATTACHMENT Filed March 24 1930 v H I Inventor -7 550CH/VEA.

A iforney Patented Sept. 1, 1931 JACOB BOCHNEK, OF BROOKLYN, NEW YORKBRUSH HANDLE ATTACHMENT Application filed March 24, 1930. Serial No.438,434.

This invention relates to improvements in brush handle attachments andhas particular reference to a simple and novel means of removablyconnecting a handle member to a brush head.

The primary object of the invention resides in a handle attachment whichfacilitates the reversal of the brush head upon the handle to permit thebrush head to be turned when the bristles along one side become worn,

thus the brush may be worn down evenly 011 v both sides during use whichprolongs the life of the same. I

Another object is to provide a brush attachment which includes a socketmember having a flattened cross plate at the outer end thereof which isnotched or slotted inwardly to facilitate the sliding attachment of thesame to a pair of spaced clamping screws carried by the brush head, thesaid screws adapted to be tightened down upon the plate to firmly thehandle member.

A further object is to provide a detachable 2 and reversible handleattachment which is extremely simple in construction, inexpensive ofmanufacture, and easily attached to brushes now in use.

With these and other objects in View, the

invention resides in the certain novel construction, combination andarrangement of parts, the essential features of which are hereinafterfully described, are particularly pointed out in the appended claim andare illustrated in the accompanying drawings, in

which:

Figure 1 is a perspective view showing my improved brush attachment withthe handle and brush head in separated condition.

Figure '2 is an enlarged detail vertical transverse sectional viewthrough the brush head showing the handle in attached position to thehead. v

Referring to the drawings by reference characters, the numeral 10designates a brush head in its entirety which includes a brush back 11with the usual bristles 12 mounted therein. countersunk in the top faceof the brush back 11 centrally thereof is a metal rectangular shapedplate 13 which is fasclamp the brush head to tened to the brush back byscrews or like fastening elements 14. Threaded into the plate 13 atspaced distances are clamping screws 15, each of which includes aclamping head 16,

. and an outer manipulating head 17.

Associated with the brush head 10 is a handle member 18, one end ofwhich fits into a socket member 19, the said socket member carrying afiat rectangular shaped cross plate 20 of a size and shape similar tothemetal wear plate 13 embedded in the brush head 11.. The cross plate 20on opposite sides of the axis of the socket19 is provided with inwardlyextending slots or notches 21, both notches opening onto one of thelongitudinal side edges of the said plate 20.

In order to attach the handle member 18 to the brush head 10, theclamping screws 15 are screwed outwardly toenable the cross plate 20 tobe slid into position directly above the metal wear plate 13, the slot21 accommodating the threaded shank of the clamping screws 15. When theclosed ends of the slots 21 abut the shanks of the clamping screws, theplates 20 and 13 are in alinement after which the clamping screws areturned by grasping the manipulating heads 17 so as to cause the clampingheads 16 to tightly engage the top of the cross plate 20. After theclamping screws have been tightened down. the handle member 18 is firmlyconnected to the brush head 10 whereupon the brush may be put into use.It will be appreciated that in time, one of the sides of the bristles 12may become worn, whereupon the 35 clamping screws 15 may be loosened,and the handle member reversed so that what was once the front of thebrush is now therear, and which reversal of the handle serves to prolongthe life of the brush.

From the foregoing description it will be seen that I have provided anovel and simple connection between the handle member and the brush headof a sweeping brushin which 95 the two parts may be quickly and firmlyconnected together and disconnected when de sired to reverse theposition of the brush with respect to the handle member.

Having thus described the invention, what 1 I claim as new and desire tosecure by Letters Patent is In combination with a brush having a brushback and a handle therefor, the top face of said brush back having arectangular shaped recess therein, a rectangular shaped metal plateseated in said recess and held by fastening screws passing throughopenings therein and threaded into the bottom of said recess, said platebeing flush with the top of said brush back, spaced threaded openingsprovided in said plate, double headed screws threaded into said threadedopenings, asobket member fitting onto one end of said handle, a fiatplate carried by said socket member and extending transversely of thelongitudinal axis thereof, said plate having spaced slot-s extendinginwardly from the outer side edge thereof for receiving the threadedshanks of said screws, while said screws are adapted tobe screwed intothe threaded openings inisaid first plate until the lower ends of thedouble heads of Silld screws bears .against the plate on said socketmember to vsecurely connect the brush and handle to- .gether. I I

in testimony whereof I afiix my signature.

JACOB BOCHNEK.
